DArT markers: diversity analyses, genomes comparison, mapping and integration with SSR markers in Triticum monococcum

Abstract: Triticum monococcum (2n = 2x = 14) is an ancient diploid wheat with many useful traits and is used as a model for wheat gene discovery. DArT (D iversity Ar rays T echnology) employs a hybridisation-based approach to type thousands of genomic loci in parallel. DArT markers were developed for T. monococcum to assess genetic diversity, compare relationships with hexaploid genomes, and construct a genetic linkage map integrating DArT and microsatellite markers. A DArT array, consisting of 2304 hexaploid wheat, 1536 tetraploid wheat, 1536 T. monococcum as well as 1536 T. boeoticum representative genomic clones, was used to fingerprint 16 T. monococcum accessions of diverse geographical origins. In total, 846 polymorphic DArT markers were identified, of which 317 were of T. monococcum origin, 246 of hexaploid, 157 of tetraploid, and 126 of T. boeoticum genomes. The fingerprinting data indicated that the geographic origin of T. monococcum accessions was partially correlated with their genetic variation. DArT markers could also well distinguish the genetic differences amongst a panel of 23 hexaploid wheat and nine T. monococcum genomes. For the first time, 274 DArT markers were integrated with 82 simple sequence repeat (SSR) and two morphological trait loci in a genetic map spanning 1062.72 cM in T. monococcum. Six chromosomes were represented by single linkage groups, and chromosome 4Am was formed by three linkage groups. The DArT and SSR genetic loci tended to form independent clusters along the chromosomes. Segregation distortion was observed for one third of the DArT loci. The Ba (black awn) locus was refined to a 23.2 cM region between the DArT marker locus wPt-2584 and the microsatellite locus Xgwmd33 on 1Am; and the Hl (hairy leaf) locus to a 4.0 cM region between DArT loci 376589 and 469591 on 5Am. DArT is a rapid and efficient approach to develop many new molecular markers for genetic studies in T. monococcum. The constructed genetic linkage map will facilitate localisation and map-based cloning of genes of interest, comparative mapping as well as genome organisation and evolution studies between this ancient diploid species and other crops.

Decentering as a Potential Common Mechanism across Two Therapies for Generalized Anxiety Disorder

Abstract: Objective To examine decentering as a potential mechanism of action across two treatments for generalized anxiety disorder: an acceptance based behavioral therapy (ABBT) and applied relaxation (AR).

The demography of introduction pathways, propagule pressure and occurrences of non-native freshwater fish in England

Abstract: 1. Biological invasion theory predicts that the introduction and establishment of non-native species is positively correlated with propagule pressure. Releases of pet and aquarium fishes to inland waters has a long history; however, few studies have examined the demographic basis of their importation and incidence in the wild. 2. For the 1500 grid squares (10×10 km) that make up England, data on human demographics (population density, numbers of pet shops, garden centres and fish farms), the numbers of non-native freshwater fishes (from consented licences) imported in those grid squares (i.e. propagule pressure), and the reported incidences (in a national database) of non-native fishes in the wild were used to examine spatial relationships between the occurrence of non-native fishes and the demographic factors associated with propagule pressure, as well as to test whether the demographic factors are statistically reliable predictors of the incidence of non-native fishes, and as such surrogate estimators of propagule pressure. 3. Principal coordinates of neighbour matrices analyses, used to generate spatially explicit models, and confirmatory factor analysis revealed that spatial distributions of non-native species in England were significantly related to human population density, garden centre density and fish farm density. Human population density and the number of fish imports were identified as the best predictors of propagule pressure. 4. Human population density is an effective surrogate estimator of non-native fish propagule pressure and can be used to predict likely areas of non-native fish introductions. In conjunction with fish movements, where available, human population densities can be used to support biological invasion monitoring programmes across Europe (and perhaps globally) and to inform management decisions as regards the prioritization of areas for the control of non-native fish introductions. © Crown copyright 2010.

Microvascular response to tissue injury and capillary ultrastructure in the foot skin of type I diabetic patients.

Abstract: 1. Microvascular blood flow responses to injury and capillary ultrastructure were assessed by laser Doppler flowmetry and detailed light and electron microscopy respectively in skin biopsied from 28 patients with insulin-dependent diabetes and 17 control subjects. 2. The hyperaemic response induced by biopsy ( P P P 3. Skin capillary basement membrane thickness was significantly increased in the diabetic patients ( P P P P 4. Basement membrane thickness was related significantly to the impaired hyperaemic response to both biopsy ( P P 5. Our findings support the hypothesis that structural abnormalities, which are characterized by an early reduction in capillary size and later thickening of basement membrane, form an important mechanism for the impaired hyperaemic response in diabetic patients.

Framing and Organizational Misconduct: A Symbolic Interactionist Study

Abstract: This study expands theoretical understanding of organizational misconduct through qualitative analysis of widespread deceptive sales practices at a large U.S. life insurance company. Adopting a symbolic interactionist perspective, this research describes how a set of taken-for-granted interpretive frames located in the organization’s culture created a worldview through which deceptive sales practices were seen as normal, acceptable, routine operating procedure. The findings from this study extend and modify the dominant theoretical ‘pressure/opportunity’ model of organizational misconduct by proposing that the process engine driving misconduct is not amorally rational organization members, but rather is organizational members acting on socially constructed views of the organization that normalize misconduct.
